Three ways to use rippr
🌐 Website — rippr.me
Paste a YouTube URL, get the transcript. Clean text, no signup.
🧩 Chrome Extension — Chrome Web Store
One-click transcript extraction directly on any YouTube page. Multiple output formats (RAG, JSON, Markdown).
🤖 MCP Server — npm
Connect rippr to Claude, Cursor, or any MCP-compatible client. Saves each transcript to ~/rippr/transcripts/ and returns the file path to the model.
> **Desktop clients only.** rippr runs as a local stdio process, so it works with Claude Desktop, Claude Code CLI, and Cursor. It does not work with cloud-hosted clients (claude.ai on the web, the Claude mobile app, or Claude Code on phone / web), which can't spawn local processes.
Add to Claude Desktop (~/Library/Application Support/Claude/claude_desktop_config.json):
Then ask: *"Rip this YouTube video: [url]"*. See mcp/README.md for the full tool surface.

Output formats
- **RAG (.txt)** — single continuous text block, optimized for chunking and embedding
- **Structured (.json)** — timestamped segments with metadata
- **Readable (.md)** — markdown with headers and formatting
How it works
Multi-strategy extraction for maximum reliability:
1. **Innertube API** — YouTube's internal player API (Android client)
2. **HTML scraping** — parses ytInitialPlayerResponse from page source
3. **Transcript panel** — opens YouTube's built-in transcript panel as last resort
Caption XML parsed in multiple formats (srv3, timedtext, JSON3). Retry with exponential backoff on transient failures.
Privacy
Runs entirely on your machine. No data sent to external servers. No accounts, no tracking. Only communicates with YouTube's own APIs.
